#151870 - Dummy Bit Responding to: ???'s previous message |
Have you provided for the "dummy bit" in your protocol?
If you do not know what this is then look at the data sheet carefully. This is the first zero bit that appears on the DOUT pin right after the clock that brings out the A0 address bit on the DIN pin. This bit causes problems for many that are new to the 93C46 family of parts and can also be problematic for hardware designs that try to save a pin by connecting both DOUT and DIN of the part to the same port pin of the MCU.
